CVE-2015-0837 2 Debian, Gnupg 3 Debian Linux, Gnupg, Libgcrypt 2024-08-06 5.9 Medium
The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."
CVE-2016-6313 4 Canonical, Debian, Gnupg and 1 more 5 Ubuntu Linux, Debian Linux, Gnupg and 2 more 2024-08-06 N/A
The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
CVE-2016-4579 3 Canonical, Gnupg, Opensuse 3 Ubuntu Linux, Libksba, Leap 2024-08-06 N/A
Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via unspecified vectors, related to the "returned length of the object from _ksba_ber_parse_tl."
CVE-2016-4574 3 Canonical, Gnupg, Opensuse 4 Ubuntu Linux, Libksba, Leap and 1 more 2024-08-06 N/A
Off-by-one error in the append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.4 allows remote attackers to cause a denial of service (out-of-bounds read) via invalid utf-8 encoded data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-4356.
CVE-2016-4356 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-08-06 N/A
The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data.
CVE-2016-4354 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-08-06 N/A
ber-decoder.c in Libksba before 1.3.3 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.
CVE-2016-4355 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-08-06 N/A
Multiple integer overflows in ber-decoder.c in Libksba before 1.3.3 allow remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.
CVE-2016-4353 2 Canonical, Gnupg 2 Ubuntu Linux, Libksba 2024-08-06 N/A
ber-decoder.c in Libksba before 1.3.3 does not properly handle decoder stack overflows, which allows remote attackers to cause a denial of service (abort) via crafted BER data.
CVE-2017-9526 1 Gnupg 1 Libgcrypt 2024-08-05 N/A
In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
CVE-2017-7526 3 Canonical, Debian, Gnupg 3 Ubuntu Linux, Debian Linux, Libgcrypt 2024-08-05 N/A
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.
CVE-2017-0379 2 Debian, Gnupg 2 Debian Linux, Libgcrypt 2024-08-05 N/A
Libgcrypt before 1.8.1 does not properly consider Curve25519 side-channel attacks, which makes it easier for attackers to discover a secret key, related to cipher/ecc.c and mpi/ec.c.
CVE-2018-1000858 3 Canonical, Gnupg, Redhat 3 Ubuntu Linux, Gnupg, Enterprise Linux 2024-08-05 N/A
GnuPG version 2.1.12 - 2.2.11 contains a Cross ite Request Forgery (CSRF) vulnerability in dirmngr that can result in Attacker controlled CSRF, Information Disclosure, DoS. This attack appear to be exploitable via Victim must perform a WKD request, e.g. enter an email address in the composer window of Thunderbird/Enigmail. This vulnerability appears to have been fixed in after commit 4a4bb874f63741026bd26264c43bb32b1099f060.
CVE-2018-12020 4 Canonical, Debian, Gnupg and 1 more 10 Ubuntu Linux, Debian Linux, Gnupg and 7 more 2024-08-05 7.5 High
mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes.
CVE-2018-9234 2 Canonical, Gnupg 2 Ubuntu Linux, Gnupg 2024-08-05 N/A
GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey.
CVE-2018-6829 1 Gnupg 1 Libgcrypt 2024-08-05 N/A
cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation.
CVE-2018-0495 5 Canonical, Debian, Gnupg and 2 more 14 Ubuntu Linux, Debian Linux, Libgcrypt and 11 more 2024-08-05 N/A
Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
CVE-2019-14855 3 Canonical, Fedoraproject, Gnupg 3 Ubuntu Linux, Fedora, Gnupg 2024-08-05 7.5 High
A flaw was found in the way certificate signatures could be forged using collisions found in the SHA-1 algorithm. An attacker could use this weakness to create forged certificate signatures. This issue affects GnuPG versions before 2.2.18.
CVE-2019-12904 2 Gnupg, Opensuse 2 Libgcrypt, Leap 2024-08-05 5.9 Medium
In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the vendor's position is that the issue report cannot be validated because there is no description of an attack
CVE-2019-13050 6 F5, Fedoraproject, Gnupg and 3 more 6 Traffix Signaling Delivery Controller, Fedora, Gnupg and 3 more 2024-08-04 7.5 High
Interaction between the sks-keyserver code through 1.2.0 of the SKS keyserver network, and GnuPG through 2.2.16, makes it risky to have a GnuPG keyserver configuration line referring to a host on the SKS keyserver network. Retrieving data from this network may cause a persistent denial of service, because of a Certificate Spamming Attack.
CVE-2020-25125 2 Gnupg, Gpg4win 2 Gnupg, Gpg4win 2024-08-04 7.8 High
GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG 2.2.23 is a fixed version.
